I'm trying to watch video from my Netbook on my HDTV. Video is great but no sound.

Netbook is HP Mini 311 1027TU running XP
TV is Panasonic LED with 4 HDMI inputs

Plugged the cable in both ends
Set the NVIDIA to two screens spanned

Picture is good but no sound.
Have loaded new IDT Audio driver - same.

Have tried rebooting each machine either first or second.

Google suggests right-clicking the Sound icon (in control panel) and selecting HDMI on the Playback tab - but doing this on my system does NOT give me a Playback tab - I can see no reference to HDMI in the sound utility. I have tried setting the sound output ti each of the several options (eg headphones, laptop speakers, monitor speakers, surround 5.1 etc etc). No Joy.

I can hook up the headphone output from the netbook to RCA audio-in on the TV but that sound presents on AV3 - whereas the picture is on HDMI4

Any suggestions of what I can try from here?

Hi Mauricio
but as I said

Are you sure your laptop can actually send audio over HDMI?

Don't have an XP system here, but try this: 

- Right-click the speaker icon in the system tray tray
- Select "Playback devices"
- Right-click over any of the displayed devices
- Select "Show disabled devices"

Go from there, good luck :-)

One out of the four hdmi ports on my Samsung tv won't produce sound, it so happens to be the one labeled DVI. have you tried another port?

1. No I'm not sure. I assumed that if a machine was provided with an HDMI port, it would be able to send both picture and sound. How do I find out?

2. As I said, I today downloaded and installed the latest sound driver. It's a netbook so I guess it doesn't have an HDMI card. I don't know how to find out what type of driver it is using.

3. As I said before, my Sound utility doesn't give me a "playback" tab - otherwise I would have done exactly as you suggest.

4. Plod, thanks for that suggestion: I'll try that tomorrow.

I see you have updated the sound drivers. But isn't the sound over HDMI via the video Nvidia ION?

Have you tried updating the Nvidia drivers? Or if they are up to date....perhaps try an older version.

I didn't know that, but anyway, I updated those today too: but no difference :-(
Thanks for your suggestion, though.

I can only suggest you Google Nvidia ION no sound hdmi. I am only suggesting Google as there were quite a few results and too many suggested fixes to list.

Only other thing I can think of....perhaps in the nvidia control panel there is some tick box or option to turn on/enable or force sound out over the HDMI. I am guessing this I have 3 ati cards and the only one nvidia (in my gaming rig)...I don't use the HDMI video out to the tv.

Hi Azzura
Have just had a look at the Nvidia Control Panel and there is no mention of either sound or HDMI anywhere - just picture stuff.

I'll google the term you suggest, however. I've looked at lots of thr Google results already with no joy. All seem to assume that when I open Control Panel>Sound that I have a Playback tab - which I don't.

I also meant to say...any chance it could be a bad cable? Have you tried another HDMI cable. Or tried your current HDMI with another device to verify it is working fine?

Hmm. Brand new to HDMI and don't have any other HDMI devices to try. This is a brand new cable and I'm not keen on buying another when, reading the internet traffic on this question, it is a very common problem.
